74HC373D,652

Product Overview

The Nexperia USA Inc. 74HC373D,652 is a surface-mount logic device in the 74HC series, supplied as a 20-SO package. It implements one D-type transparent latch with an 8:8 circuit arrangement and tri-state outputs. The device operates from a 2V ~ 6V supply and supports an operating temperature range of -40°C ~ 125°C.

Key Features

• D-type transparent latch logic function with one independent circuit.
• 8:8 circuit configuration for parallel data paths.
• Tri-state output type for bus connection control.
• Supply voltage range of 2V ~ 6V.
• Propagation delay of 12ns.
• Output high and low current of 7.8mA, 7.8mA.
• Operating temperature range of -40°C ~ 125°C.
• Surface-mount 20-SOIC package with 0.295" (7.50mm) width.

Applications

• Temporary retention of parallel control or data values in digital logic circuits.
• Bus-facing interfaces where tri-state outputs are used to isolate a latch from shared lines.
• Signal buffering between system logic blocks that use a 2V ~ 6V supply.

Design & Procurement Notes

When selecting the 74HC373D,652, confirm that the 2V ~ 6V supply range and 7.8mA output high and low current are compatible with the surrounding logic family and load conditions. The 12ns propagation delay should be included in timing calculations for parallel data paths. The single independent circuit indicates one 8:8 latch function, rather than multiple separate latch banks. For physical design, use the surface-mount 20-SOIC footprint corresponding to 0.295" (7.50mm) width and the 20-SO supplier device package. The -40°C ~ 125°C operating temperature range should be checked against the intended environment.
